Referring to fig. 1 to 14 together, the head-mounted display device provided by the present invention includes a housing 1, and a flexible display screen 10, a first receiving shaft 20, and an optical lens 30 disposed in the housing 1. The housing 1 further comprises a display window 40. The housing 1 is capable of switching the first light transmittance and the second light transmittance. The flexible display screen 10 comprises a display area 11 and a light transmissive area 12. The optical lens 30 is disposed corresponding to the display area 11. The flexible display screen 10 is coupled to the first receiving shaft 20. When the head-mounted display device is immersed, as shown in fig. 1, the housing 1 switches the first light transmittance, and at this time, the housing 1 is in a non-light-tight state, and light emitted from the display area 11 of the flexible display screen 10 is projected out of the housing 1 through the optical lens 30 and then through the display window 40, so as to provide a user with an immersion view of the display content of the display screen. When the head-mounted display device is transmissive, as shown in fig. 2, the housing 1 switches the second light transmittance, and at this time, the housing 1 is in a light transmittance state, the accommodating shaft 20 rotates in the direction shown in fig. 2 to drive the flexible display screen 10 to rotate, so that the light transmittance region 12 is arranged corresponding to the optical lens 30, and external light is projected out of the housing 1 through the light transmittance region 12 of the flexible display screen 10, the optical lens 30 and the display window 40, so as to provide a user with a transmissive view on external scenes. It should be understood that the directions shown in the drawings are only for illustrative purposes and are not intended to limit the present invention, as long as the first receiving shaft 20 rotates to drive the flexible display to rotate, so that the light-transmitting region 12 can project the external light through the display window 40 to provide the user with the external view. And the display area of the flexible display screen is driven by the rotation of the first accommodating shaft 20 to correspondingly act on the projected light path, so that the display content can be projected through the display window 40 to provide the user with the view of the display content.
Optionally, the head-mounted display device provided by the present invention further includes a total reflection lens 50, configured to change a projection direction of the display light source of the flexible display screen 10 after passing through the optical lens 30 to a projection direction through the display window 40. The display area 11, the optical lens 30 and the total reflection lens 50 are disposed along a first optical axis 60, and the total reflection lens 50 and the display window 11 are disposed along a second optical axis 70. When the first optical axis 60 and the second optical axis 70 form an included angle, the optical lens 30 can be positioned in a non-line of sight range viewed by a user through the display window 40. So that a real world scene not presented by the optical lens 30 can be viewed directly. Illustratively, the total reflection mirror 50 has an angle of 45 ° with the first optical axis 60, and the first optical axis 60 and the second optical axis 70 are at 90 °. When the head-mounted display device is in an immersive state, as shown in fig. 3, when the housing 1 switches the first light transmittance, light emitted from the display area 11 passes through the optical lens 30 and the total reflection lens 50 and is projected out of the housing 1 through the display window 40, so as to provide a user with an immersive view of the display content of the display screen. Preferably, when the head-mounted display device is transmissive, as shown in fig. 4, when the housing 1 switches the second light transmittance, the total reflection lens 50 moves out of the second optical axis 70, the first storage shaft 20 rotates according to the direction shown in fig. 4 to drive the flexible display screen 10 to rotate, so that the light transmission region 12 of the flexible display screen 10 corresponds to the display window 40, and external light projects out of the housing 1 through the light transmission region 12 of the flexible display screen 10 and the display window 40, so as to provide a user with a transmissive view of external scenes.
Alternatively, as shown in fig. 5 to 8, fig. 5 to 8 are schematic structural diagrams of the flexible display screen 10 according to the embodiment of the present invention. When the head-mounted display device is immersed, as shown in fig. 5, the display region 11 of the flexible display screen 10 is disposed corresponding to the display window 40, and when the head-mounted display device is transmissive, as shown in fig. 6 to 8, the light transmissive region 12 of the flexible display screen 10 is disposed corresponding to the display window 40.
It should be noted that the housing 1 is a housing 1 of a display end of a head-mounted display device provided by the present invention, and fig. 1 to fig. 4 are schematic cross-sectional views of the display end of the head-mounted display device provided by the present invention. For example, the first light transmittance is 0% to 1%, and the second light transmittance is 90% to 99.5%. When the housing 1 is switched from the first light transmittance to the second light transmittance, the region of the housing 1 where the light transmittance can be switched may be the whole housing 1, or may be a partial region of the housing 1, for example, the region may be the opposite side of the housing 1 where the display window 40 is located. The invention is not limited.
Alternatively, the optical lens 30 may be detachably replaced.
Optionally, as shown in fig. 4, the total reflection mirror 50 is connected to the optical shutter 80, when the optical shutter 80 is in the bounce state, the total reflection mirror 50 moves out of the second optical axis 70, and when the optical shutter 80 is in the drop state, the total reflection mirror 20 moves into the second optical axis 70.
Specifically, the optical lens 50 is connected to the shutter 80, and when the shutter 80 is in the bounce state, the optical lens 50 is removed from the second optical axis 70, so that the external light incident through the housing 1 can be directly projected through the display window 40 to provide the user with a transparent view of the external scene. When the shutter 80 is in the falling state, the optical lens 50 moves into the second optical axis 70, so that the light emitted from the display area 11 of the flexible display screen 10 is projected to the display window 40 through the optical lens 30 and the reflection of the optical lens 50, and is projected out of the housing 1. Here, the shutter 80 may be connected to a controller of the head-mounted display device, so that the controller acquires an operation of the user to trigger the shutter 80 to rise and fall according to the input unit. For example, the input unit may be a physical button, a touch pad, or the like, and the shutter 80 is electrically controlled to be opened or closed. Shutter 80 may also be directly connected to an operable member that opens to the exterior of housing 1 so that a user may manually operate the operable member to cause shutter 80 to rise and fall. It is to be understood that the drawings are merely illustrative of the principles of the invention and are not limited to the specific structural positions shown in the drawings. When the head-mounted display device is in an immersive state, the display area 11 of the flexible display screen 10 is rotated to a position corresponding to the optical lens 30. The optical lens 30 projects the light emitted from the display area 11 of the flexible display screen 10 to the eyes of the user through the display window 40 according to a designed optical path according to a specific optical design. Similarly, the optical lens 30 is not limited to the illustrated position of the embodiment, and the light source of the display area 11 of the flexible display screen 10 may be projected to the user's eye through the display window 40 by a specific optical design, for example, the light path is changed by using a reflective element to obtain the final emitting direction.
As shown in fig. 9, the flexible display panel 10 may be formed on a flexible base tape 13 for the display area 11, and the first storage shafts 20 at both ends may be connected by the flexible base tape 13. When the first accommodating shaft 20 rotates, the flexible base band 13 is driven to rotate, and the display area 11 is moved. As shown in fig. 9A, the light-transmitting area 12 may be a hollow portion of the flexible base tape 13, so as to realize perspective. When the flexible substrate 13 is made of a transparent material, as shown in fig. 9B, the non-display area 11 is the light-transmitting area 12. It is to be understood that the drawings are merely schematic and are not intended to limit the specific locations, shapes, sizes, dimensions, arrangements, etc.
Optionally, a surface of the optical lens 50 close to the optical lens 30 is plated with a visible light band total reflection film, and a surface of the optical lens 50 far from the optical lens 30 is a frosted surface.
Wherein, the visible light wave band total reflection film is used for totally reflecting the visible light wave band from 380nm to 780 nm. The total reflection film may be a total dielectric reflection film or a metal reflection film. The all-dielectric reflecting film is a thin film plated by using a non-metallic compound material. The metal reflective film is a thin film plated with a metal material.
Optionally, the light transmissive region 12 comprises a photochromic material.
For example, the photochromic material is photochromic glass, which changes its color when irradiated with light of a suitable wavelength, and recovers its original color when the light source is removed, for example, the photochromic material has high light intensity, deep color and low transmittance. On the contrary, the light intensity is low, the color of the glass is light, and the transmittance is high. It can be seen that the light-transmitting area 12 is provided with the color-changing glass, so that the light transmittance can be adjusted through the light color change of the color-changing glass, human eyes can adapt to the change of ambient light, and the visual fatigue is reduced, thereby playing a role in protecting the eyes.
Optionally, the housing 1 includes an electrochromic material, and the housing 1 can switch the first light transmittance and the second light transmittance by electric control.
For example, electrochromic refers to a phenomenon that under the action of an external electric field, the valence state and chemical components of a material are reversibly transformed, and under the action of an external voltage, the material with electrochromic characteristics changes the structure, optical properties and thermal properties of the material due to the injection and extraction of electrons or ions. For example, in the case of equipotential or no power application, the electrochromic material is in a transparent state, and the light transmittance of the housing 1 is the second light transmittance, and in the case of existence of pressure difference, the electrochromic material displays a black state (opaque or light-shielding state), and the light transmittance of the housing 1 is the first light transmittance. Wherein the electrochromic material may be tungsten oxide WO3IrO (iridium oxide)2Or molybdenum oxide MoO3And the like.
Optionally, the housing 1 includes a second shielding body 100 and a second receiving shaft 110, the second shielding body 100 and the second receiving shaft 110, the second shielding body 100 is made of a flexible material, the second shielding body 100 is connected to the second receiving shaft 110, and the second shielding body 100 is received on the second receiving shaft 110 through the second receiving shaft 110, so that the housing 1 is switched from the first light transmittance to the second light transmittance.
For example, as shown in fig. 10, the area of the housing 1 corresponding to the second shielding body 100 is made of a light-transmitting material, and when the second accommodating shaft 110 rotates in the direction shown in fig. 10 to accommodate the second shielding body 100 on the second accommodating shaft 110, the light transmittance of the housing 1 is switched from the first light transmittance to the second light transmittance. Specifically, as shown in fig. 11, the second shielding body 100. In another embodiment, second shielding body 100 includes light-transmitting portion 100T in addition to light-shielding portion 100B. When the head-mounted display device is immersed, the light-shielding portion 100B of the second shielding body 100 shields the light-transmitting material of the housing 1, and the light-transmitting portion 100T may be partially or completely wound around the second receiving shaft 110. When the head-mounted display device is in the transmissive mode, the light-transmissive portion 100T of the second shielding body 100 is disposed on the light-transmissive portion of the housing 1, and the light-shielding portion 100B may be partially or completely rolled up on the second receiving shaft 110. The light shielding portion 100B and the light transmitting portion 100T are switched to move by the rotation of the second storage shaft 110.
Optionally, the head-mounted display device further includes a first adjusting mechanism 120, the first adjusting mechanism 120 is connected to the second accommodating shaft 110, and the second accommodating shaft 110 is driven to rotate by the first adjusting mechanism 120.
Optionally, the head-mounted display device further includes a second adjusting mechanism 130, the second adjusting mechanism 130 is connected to the first accommodating shaft 20, and the second adjusting mechanism 130 drives the first accommodating shaft 20 to rotate.
For example, as shown in fig. 12, in order to facilitate the user to control the rotation of the first receiving shaft 20 and the first receiving shaft 110, the head-mounted display device disclosed in the present invention further includes a first adjusting mechanism 120 and a second adjusting mechanism 130, wherein the first adjusting mechanism 120 can control the second receiving shaft 110 to rotate, such as the first adjusting mechanism 120 rotates clockwise, the second shielding body 100 is received in the second receiving shaft 110, the first adjusting mechanism 120 rotates counterclockwise, the second shielding body 100 is unfolded, the second adjusting mechanism 130 can control the first receiving shaft 20 to rotate, such as the second adjusting mechanism 130 rotates clockwise, the flexible display 10 is received in the first receiving shaft 20, and the second adjusting mechanism 130 rotates counterclockwise, and the flexible display 10 is unfolded.
Optionally, the housing 1 includes a detachable first shielding body 90, and the first light transmittance and the second light transmittance can be switched by detaching or attaching the first shielding body 90.
For example, as shown in fig. 12, when the detachable first shielding body 90 is detached from the housing 1, the light transmittance of the housing 1 is the second light transmittance, and when the first shielding body 90 is installed on the housing 1, the light transmittance of the housing 1 is the first light transmittance, it can be understood that the first shielding body 90 shown in fig. 12 is only a schematic diagram of an embodiment of the present invention, and is not limited to the specific structural position and size in the drawings.
Optionally, the head-mounted display device provided by the present invention further includes a protective lens disposed on the display window 40. The protective lens can prevent external dust and the like from entering the shell 1 to influence the optical element and the presenting effect thereof.
It can be seen that, according to the head-mounted display device disclosed by the present invention, when the housing 1 switches the first light transmittance, light emitted from the display region 11 of the flexible display screen 10 is projected out of the housing through the display window via the optical lens 30, so as to provide a user with an immersive view on the display content of the display screen, when the housing 1 switches the second light transmittance, the first storage shaft 20 drives the flexible display screen to rotate, so that the light-transmitting region 12 of the flexible display screen 10 is disposed corresponding to the display window 40, and external light is projected out of the housing 1 through the display window 40 via the light-transmitting region 12, so as to provide the user with a penetrable view on an external scene.
Alternatively, as shown in fig. 13-14, based on the principle of the present invention, when the display area 11 of the flexible display screen 10 is larger than the area a that can be projected by the optical lens 30, the area a is the imaging area that can be viewed by the actual user. Therefore, the actual content viewing angle that can be displayed in the display area 11 can be much larger than the visual viewing angle of the user, and when the user wants to move to another viewing angle for viewing according to the display content that is viewed in the current imaging area, the first receiving shaft 20 can rotate to drive the display area 11 of the flexible display screen 10 to move, so as to correspond to the target display area a corresponding to the viewing angle that is to be viewed. Therefore, the effect of VR visual angle transfer can be realized, the image content to be displayed by the display screen can be obtained without complex image data calculation, and the problem of delayed visual angle switching caused by insufficient calculation capability in the conventional VR technology is solved. As an embodiment, the head-mounted display apparatus further includes a sensing device 140, such as an acceleration/geomagnetic sensing device, and the like, and a controller 150. The sensing device 140 is used for sensing the moving orientation of the head of the user. When the sensing device 140 senses a movement direction (e.g., a rotation angle, a displacement) of the head of the user, the sensing device 140 transmits the movement direction to the controller 150, the controller 150 determines a corresponding target display area, a target rotation direction of the first storage shaft 20 and a target rotation amount of the first storage shaft 20 according to the movement direction, and the controller 150 controls the first storage shaft 20 to rotate according to the target rotation direction and the target rotation amount, so that the target display area is disposed corresponding to the optical lens 30, and finally, the user can view the display content of the target display area through the display window 40. For example, it can be seen that the imaging area of the display area 11 projected corresponding to the optical lens is changed by rotating the first storage shaft 20, thereby realizing that VR can see a virtual picture of a relative orientation according to the user's head rotation. The problem that in the prior art, when a user rotates the head, display data of a corresponding direction needs to be obtained through calculation, and due to the fact that the existing calculation capacity is insufficient, the switching of the visual angle is delayed is solved. In another embodiment, the rotation of the first storage shaft 20 may be controlled by a mechanical structure to switch the viewing angle, for example, the second adjustment mechanism 130. It is also possible to implement an input operation through an input unit of the head-mounted display device, and the controller 150 performs corresponding viewing angle switching according to an input signal of the input unit. The input signal (including coordinates, displacement, path, etc. of the input signal) and the view angle switching have a preset corresponding relationship. For example, the controller 150 determines a corresponding target display region according to the input signal, and based on the target display region obtaining a target rotation direction of the first storage shaft 20 and a target rotation amount of the first storage shaft 20, the controller 150 controls the first storage shaft 20 to rotate according to the target rotation direction and the target rotation amount so that the target display region is disposed corresponding to the optical lens 30. It is understood that the sensing device 140 includes an input unit having a sensing function, for example, a touch panel can sense a touch signal, and acquire a corresponding target display area, a target rotation direction and/or a target rotation amount according to a preset touch signal. The system can also be an infrared sensing device, can acquire user gestures, an iris detection device, a user gazing direction and the like. The scheme can be combined with any input mode of the head-mounted display device to acquire the target display area.
In other forms, the flexible display screen 10 may also include a plurality of display areas a, and each display area a corresponds to display content at a different viewing angle. And obtaining a corresponding target rotation direction and a corresponding target rotation amount according to the obtained target display area, so that the optical lens 30 corresponding to the target display area becomes an imaging area for a user to watch.
